What does SandBlast Threat Emulation primarily focus on?

SandBlast Threat Emulation is primarily designed to identify zero-day vulnerabilities in files. This technology analyzes files in a secure environment to detect malicious content that traditional antivirus programs may miss, especially threats that exploit unknown vulnerabilities. By executing files in a virtual sandbox, SandBlast can observe their behavior without risking the endpoint or network, leading to the early detection of sophisticated attacks that utilize zero-day exploits. This proactive assessment helps organizations defend against files that appear benign but may contain harmful codes, such as malware or ransomware.

The other options, while they address important aspects of cybersecurity, do not capture the primary focus of SandBlast Threat Emulation. Delivering original files to the end user does not align with the purpose of threat emulation, which is concerned with analyzing files rather than just passing them through. Monitoring user activity focuses more on behavior analytics than on file vulnerability detection, and ensuring safe downloads is more about filtering and validating files before they reach the user, rather than examining them for hidden threats.
